  5. The Night Sky Friday, February 17· This is the time of year when, after dinnertime, the W pattern of Cassiopeia stands vertically on end high in the northwest. Saturday, February 18· After dinnertime at this time of year, four carnivore constellations stand in a row from the northeast to south. They're all seen in profile with their noses pointed up and their feet (if any) to the right: Ursa Major in the northeast (with the Big Dipper as its brightest part), Leo in the east, Hydra the Sea Serpent in the southeast, and Canis Major in the south.  Sunday, February 19· We're in the dark of the Moon, which means it's deep-sky observing time. Check out a dozen winter planetary nebulae using your star atlas and Ted Forte's guided tour with pictures in the February Sky & Telescope, page 60. Monday, February 20· Brilliant Sirius shines highest due south around roughly 8:30 or 9 p.m., depending on how far east or west you live in your time zone. · Have you ever seen Canopus, the second-brightest star after Sirius? In one of the many interesting coincidences that devoted skywatchers know about, Canopus lies almost due south of Sirius: by 36°. That's far enough south that it never appears above your horizon unless you live below latitude 37° N (southern Virginia, southern Missouri, central California). And even there you'll need a flat south horizon. Canopus transits the sky's north-south meridian just 21 minutes before Sirius does. When to look? Canopus transits right when Beta Canis Majoris (Mirzim) does. That's the fairly bright star about three finger-widths to Sirius's right. When Mirzim is due south, look straight down from there.
